Abstract: The present invention discloses a focusing method using axial chromatic aberration and an exemplary optical inspection architecture based on such method. Sample planes of different depths are by nature brought into focus by different spectral parts of light via an optical imaging system, which equivalently means that different spectral parts of light reveal different degrees of in-focus for any specific sample plane. The degree of in-focus corresponds to a quantitative index that is derived algorithmically, and lights of different wavelength bear distinct quantitative indices with respect to each specific sample plane. A bunch of quantitative indices are used to build a lookup table comprising index ratios between different wavelengths. Only one image needs to be captured on the production line for each inspection point, and such image is then filtered into a first-waveband image and a second-waveband image whence their corresponding quantitative indices regarding the degree of in-focus are obtained. According to the ratio of the two quantitative indices, the corresponding position parameter can be deduced from the lookup table, whose information guides the optical inspection system toward the expected focal position without multiple scanning over a suspicious spatial range.

Abstract: The invention relates to a method for the production of a steel sheet having a fully martensitic structure with an average lathe size of less than 1 micrometre, the average elongation factor of the lathes being between 2 and 5, wherein the elongation factor of a lathe of maximum dimension lmax and minimum dimension Imin is defined as<sub/>Imax / Imin, with a yield point greater than 1300 MPa, and mechanical strength greater than (3220(C)+958) megapascals, (C) denoting the carbon weight content of the steel. The method comprises the following steps consisting in: supplying a semi-finished steel product having a composition containing, expressed as weight, 0.15% = C = 0.40%, 1,5% = Mn = 3%, 0.005% = Si = 2%, 0.005% = Al = 0.1 %, 1.8% = Cr = 4%, 0% = Mo = 2%, wherein 2.7% = 0.5 (Mn)+(Cr)+3(Mo) = 5.7%, S = 0.05%, P = 0.1 % and, optionally, 0% = Nb = 0.050%, 0.01 % = Ti = 0.1 %, 0.0005% = B = 0.005%, 0.0005% = Ca = 0.005%, the remainder of the composition being formed by iron and the inevitable impurities resulting from production; heating the semi-finished product to a temperature T1 between 1050°C and 1250°C and, subsequently, subjecting the heated semi-finished product to rough rolling at a temperature T2 between 1000 and 880°C, with a cumulative reduction rate µa greater than 30%, such as to obtain a sheet having an austenitic structure that is totally recrystallised, with an average grain size of less than 40 micrometres and preferably less than 5 micrometres; and partially cooling the sheet, such as to prevent the transformation of the austenite, at a rate VR1 greater than 2°C/s to a temperature T3 between 600°C and 400°C in the metastable austenitic range, and, subsequently, subjecting the not completely cooled sheet to final hot rolling at temperature T3, with a cumulative reduction rate µb greater than 30%, such as to obtain a sheet that is cooled at a rate VR2 above the critical cooling rate.
